Bug#982990: Upstream fix?

[Jerome Andrieux]

I have encountered the same issue and found it was reported upstream and
apparently fixed in "devel" 9 days ago :
https://github.com/kdave/btrfs-progs/issues/339 and
https://github.com/kdave/btrfs-progs/commit/922eaa7b5472ef2b5328c71fa54868bcbb97f7ac#r46945148
